Maintenance - Greenlee HW1 Manuel De L'utilisateur

Operation (cont'd)
1. Start the power source.
Note: Allow the power source to run for a few
minutes to warm the hydraulic fluid.
2. Set the directional spool to the appropriate position
(forward or reverse).
Do not change the position of the directional spool
while the tool is operating. Allow the tool to stop
before changing direction.
Failure to observe this precaution can result in
property damage.
3. Grasp the handle. Place your other hand on the top
of the tool or on the auxiliary handle. This will allow
you to apply leverage while operating the tool.
4. To start the tool, squeeze the trigger.
• HW1V Only: Use the variable torque adjust-
ment to achieve the necessary amount of torque.
Setting "H" is for high torque, "M" is for medium
torque, and "L" is for low torque. In the illustration
below, the wrench is set to the high torque posi-
tion. Turn 90° clockwise for medium torque and
180° clockwise for low torque.
TORQUE
• HW1 and HW1V: If 5 seconds of impacting does
not loosen a bolt, nut, etc., stop impacting and
use some other method of removal. Continued
impacting will cause severe wear on the impact
mechanism.
5. To stop the tool, release the trigger.
6. When the tool is not in use, stop the power source
to reduce heat and wear on tool components.
